Abstract

PURPOSE: To make it posible to provide the use of the whole automatic photography in common by controlling the exposure in accordance with the speed of an object being photographed to be detected by an image, sensor.
CONSTITUTION: When film sensitivity value is set in the film sensitivity setting circuit 134 and sensor release is operated, the moving light of object is scanned and received by the image senaor group of alloy form Then the memory arranged to the addres corresponding to the arrangement of the image sensor group is addressed. By comparing the output of memory with the output of image sensor group, the moving speed of theobject is detected, and the output of FF 124W129 is reversed via fixed operators 50W55. Accordingly, selection circuit 137 is changed by operator 131, and diaphragm control device 140 is driven by counting the proper diaphragm value corresponding to the fixed second time of fixed setting circuit 136 in the arthmetic circuit 138 to which the brightness of photometric circuit 133 is applied. Therefore in this state, when the shutter is released, the whole automatic photographing free from the vibration of image is done even at the time of moving the object by the exposure based on the proper diaphragm
